Ok, this was non-obvious to me, so I thought I'd mention
it:

    Just because one IPSEC peer initiates the connection, it
    does not mean that same peer will initiate rekeying.

This confused me for a bit.  My openbsd box is initiating
ISAKMP negotiations and hence performs the first phase-2
keying, and sets the timeout, but my peer (altiga) is initiating
the rekeying before the openbsd box tries to, and hence every
subsequent rekeying interval is being determined by the
altiga device.
